Changes in this release:
* The internal data structure for representing the network graph was much optimized, yielding significant runtime speedups (on some cases >10x)
* New HTML output format allows presenting interactive graphs. Double clicking an endpoint on the graph hides all endpoints not connected to the selected endpoint. Clicking a source endpoint, then a destination endpoint, provides more details on why the two are connected/disconnected. In particular, which network policies are involved in this decision.
* Support for Istio's Egress Gateway
* Upgrade to Python 3.9
